Boring & Stroking 5.3l To 6.6l

This is a discussion on Boring & Stroking 5.3l To 6.6l within the Internal Engine forums, part of the LSx Technical Help Section category; I NEED TO KNOW IF IT POSIBLE TO BORE THE 5.3L FROM 3.8 TO 4.0 AND PUT A 4.0&quot; CRANK ...

Would A 383 C.i. Increase The Horse Power And Tq. Levels...
I Have Descreened The Air Flow Sensor,
Added A Daiblo Programmer, Headers, 160' Thermostat, K&n Filter With A Air Aid Induction, And A T.b. Spacer..

just slap in a cam, get rid of the diablo, stall it, and get a dyno tune. stick something like a 224 cam in and you can have some nice power. just make sure you get rid of that piece of crap g80 in your rear end before you start launching.

Thanks For The Information On The Cam And 6.0 Block...
What Is The G80.
What Works Better Than The Diablo, May Be "hp Tuners"...
I Was Very Disapointed When I Got The Results Of My Burban From The Dyno Shop...

230 H.p.
282 Lbs/tq
At The Rear Wheel... I Guess You Loss A Lot The The Transfer Case But I Need To Build Up A Lot More Power...

I Also Need To Know If Stell Blocks Have Any Liners OR Sleeves Like The Aluminum Block Do....

I Know All Ls-based Engines Have 4.4" Spacing And Sleeves Are Sold The Can Be Bored Out To 4.250"... I Have Never Opened Up An Ls- Engine... I Have A Long Block 5.3l For A Spare Eng. And I Would Like To Work On This One...
You know you are right about the diablo, the frist day I had the turner in stalled I called daiblo and asked if that was all i was going to get out of the tuner...
